John Mayer showed a customized 41mm Tudor Black Bay with a blue bezel, black dial and Undefeated branding. It was reported as a small friends-and-family gift, not a standard retail release; GQ Germany reported that 50 were made, a figure not confirmed by TUDOR.
What watch did John Mayer get from Undefeated?
Contemporary watch coverage identified it as a 41mm Tudor Black Bay customized with a blue bezel, black dial and Undefeated logo. Time+Tide also described the watch as 15mm thick. These are details reported about this particular piece, not specifications from an official TUDOR product sheet.

The combination makes the watch distinct from a standard catalog Black Bay: it pairs a recognizable dive-watch design with branding from Undefeated, the streetwear label. Time+Tide reported that Mayer called himself a longtime friend and fan of Undefeated and Union Los Angeles, and thanked Chris and the Union creative team. The article characterized the watch as a gift. Mayer’s reported reaction was “above and beyond on this one.” Time+Tide’s 2021 account attributes those remarks to his Instagram Story.
How many were made, and who received them?
GQ Germany reported in 2021 that 50 examples were made for selected Undefeated employees and friends, with each recipient’s name engraved on the case back. This is secondary reporting; TUDOR has not been cited as confirming the production number.

Can you buy the Undefeated Black Bay?
The reported distribution was not a general retail sale. No verified current listing or reliable current valuation is established here, so a buyer should not assume the custom watch is available or treat an asking price as a reliable market value.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How it differs from current TUDOR Black Bay models
TUDOR’s official Black Bay pages show an active family of catalog watches. Those models provide useful context, but they are not the Undefeated customization. For example, the official Black Bay 58 is a 39mm model, unlike the reported 41mm case on Mayer’s watch.

- Tudor Black Bay 54 Automatic Chronometer Black Dial Men's Watch M79000N-0001
If you are considering a standard Black Bay, compare the specific model’s case dimensions, thickness, dial and bezel colors, strap or bracelet, movement specifications, and local price and availability. A catalog model may share the broad look, but it is not an equivalent version of the Undefeated piece.
